Why does my Asthma Control Score say ______?

Propeller uses National Heart, Lung, and Blood Institute (NHLBI) guidelines to determine your level of asthma control. Because Propeller sensors track the date and time of your rescue uses, we’re able to say how well controlled you are based on your data.

These scores can be pretty confusing, especially if you’re new to these guidelines. If you’ve still got questions, talk to your doctor about your asthma control status and rescue inhaler use.

Propeller sensors only know what you tell them, so if you use a nebulizer or another rescue medication that doesn’t have a Propeller sensor on it, we might think you’re in better control than you are. You can track those medication uses through the Propeller app manually. For more information, see this article.
